springboot项目集成Scheduled定时任务

一.主类上开启定时任务 @EnableScheduling

@SpringBootApplication
@MapperScan(basePackages = {"com.yy.springbootdemo.dao"})
@EnableScheduling   //开启定时任务
public class SpringBootDemoApplication {
    public static void main(String[] args) {
        SpringApplication.run(SpringBootDemoApplication.class, args);
    }

}

二.定时类

package com.yy.springbootdemo.schedule;

import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
import java.util.Date;

@Configuration //表示这是一个配置类，可以被扫描到，写@Component也行
public class TimeCron {

    /**
     * 每秒执行一次。
     */
    @Scheduled(cron = "1-59 * * * * ? ")
    public void cron(){
        System.out.println(new Date());
        System.out.println(System.currentTimeMillis());
    }
}
